Alternating Current vs Direct Current - Technical MCQs
Q1: If a sine wave signal is 100 mV peak-to-peak, how many volts would be measured by a voltmeter?A 14.14 mV
B 35.4 mV
C 63.7 mV
D 70.7 mV
ANS:B - 35.4 mV Since it is 100mV pk-to-pk it need to be divided in to half to get the Vpeak only. 100mV/2 = 50mV then voltmeter always measure the RMS of an AC voltage. |
